This invention relatesto tables used inthe Y playing of pool and billiards,V andnrelates Vject, I provide a pluralityV more ,particularly to such tables as yare Vof relatively lightconstruction andintended for portable use. Insuch -portable tables it isA customary to form the bed or playing surface from a singlecontinuous sheet of some ,composite or laminated material which is of no great thickness or rigidity.' `These portable tables are commonly used on floors or foundationswhich are not carefully leveled or prepared for such use. Under these circumstances, itis verydesirable to be able to straighten or level the playing 'bed of a pool orbilliard table afterjthe table has been placed on its more orless ir# regular foundation. Y

It is the general object of my invention to provide improved means forthus straightenplayingsurface of a pool ing or leveling the or billiard table.

To the accomplishment of this general obof actuating devices by the use of which selected areas of the tablemay be relatively raised or lowered as may be advisable.

My invention further relates to arrange! ments and combinations ofparts which willl be hereinafterl describedand more particu-l larly pointed out inthe appended claims.

A preferred form of the invention is shown in the drawings, in which i e Fgl 1S a Plan View `0f Illyl improved pool or billiard table; Y v v i Fig. 2 is a detailsectional elevation,ftalien along the line 2 2 in Fig. 1 and Fig. 3 is a transverse sectional elevation,

taken along theline 3 3 in Fig. 1.

-Referring to the drawings, Ihave shown a light portable pool or billiard tablecomprising an enclosing frame 10 supported on legs ll (Fig. 2) and having the sides thereofcond nected by cross frame members. l2 loosely supporting theiendsof the playing surface or be'd 14. VThelower inside edge of the frame is recessed and retaining strips 16 (Fig. 2) are secured tothe frame l0 below the recess providing a deep groove to slidably receive the edges of the bed 14. The bed is thus somewhat loosely confined horizontally7 so i ing longitudinallyA the c Adjusting turned.` U The screwslO areV positioned: at intersece.

feipand or contract; laterally in the supporting frame-work.

L Tiibed 14 may be made` f any imitatie composite or llaminated material and is pref-i v.erably formed from a single'continjuoussheet. of limited thickness.`

In order tostifen the b ed 14, vreenforcingV bars 20 vare secured4 inl spaced relationto the under side of the bed llgand are showninfthe drawings as e'xtendi renf.
